Title: Colour picture tube screening method
IPC: H01J9/20
Filed: 1974-05-01
Abstract: 1473388 Luminescent screens for colour television tubes RCA CORPORATION 1 May 1974 [2 May 1973] 19033/74 Heading H1D A method of making a screen for a colour picture tube involving exposing a photosensitive material on a support to light which has passed through a lens having a discontinuous effective surface is characterized in that the discontinuities are masked and the lens is moved throughout the exposure. Arrangements of discontinuities described are such as to divide the lens into squares or rectangles, in which case the motion is diagonal to these, and hexagons when the motion is perpendicular to one set of sides of the hexagons. In order to even out the exposure the masking can be increased at the corners of the squares or rectangles lying on the diagonals parallel to the motion or at the sides of the hexagons perpendicular to the motion. The masking can be applied directly to the lens or to a separate sheet of glass overlying the lens. Reference has been directed by the Comptroller to Specification 1,347,949.

Title: Electric pulse modulating systems
IPC: H03K9/08
Filed: 1945-07-27
Abstract: 601,135. Pulse modulation circuits. STANDARD TELEPHONES & CABLES, Ltd. July 27, 1945, No. 19333. Convention date, July 29, 1944. [Class 40 (v)] In a pulse width modulating system, a tuned circuit is recurrently shock-excited to produce a series of undulations, the tuning being varied by the modulation voltage to vary the width of the undulations and the derived pulses. Pulses from a generator 1 shock-excite the tuned circuit 2, the diode 3 damping out the wave train after the first positive half-cycle. A modulating voltage from source 5 applied to the reactance valve 4 causes the tuning of the circuit 2 to vary, changing the width of the first positive half-cycle. This undulation is fed. through a high-pass filter 6 to a pulseshaping amplifier 7 and to a differentiating and inverting circuit 8 to produce narrow pulses coincident with the leading and trailing edges of the first pulse. Where the input pulses are of short duration, they may be converted into a saw-tooth wave, Fig. 3 (not shown), to prevent the generation of undesired waveforms by the trailing edges. Specification 600,284 is referred to.

Title: Method and apparatus for filling-in joints between pipe sections
IPC: F16L55/163
Filed: 1961-05-30
Abstract: 973,648. Repairing leaks in pipes; jointing apparatus. J. DELARUELLE, and J. LE CARRE. May 30, 1961 [May 31, 1960], No. 19474/61. Headings F2G and F2P. In a method for executing or repairing joints in pipes a strip of ductile metal or alloy carrying outwardly an adhesive is urged against the inner wall of the pipe in the region of the joint by means of an expansible or inflatable support. The metal strip which is preferably of aluminium or aluminium alloy one or a few tenths of a millimetre thick is wound round a rubber sleeve 2. The strip which has previously been roughened is coated with a polymerizable resin. The rubber sleeve 2 is secured over the ends of a tubular body 1 by reinforcements 3, 3<SP>1</SP> and wires 4, 4<SP>1</SP> and is adapted to be inflated by compressed air via passages 6, 5 and 8. One end of the apparatus carries an electronic probe 10, inside a plastic casing 11, which detects a joint. In use the apparatus is pulled through a pipe by cable 15, elastic shoes 9, 9<SP>1</SP> or rollers engaging the inner surface of the pipe, until a joint is located. The rubber sleeve 2 is then inflated to press the metal strip against the walls of the pipe. A fraction of the adhesive on the metal strip engages the recess in the joint while the remainder secures the metal strip to the pipe. The compressed air is exhausted after one or two minutes and the apparatus removed. The final release of the strip from the support may be furthered by coating the latter with a lifting material, e.g. silicone fat, talcum powder. In another embodiment a series of inflatable supports are adjustably connected together at distances corresponding to those between the joints of the pipe previously measured by a probe, so that all the joints may be filled simultaneously on inflation of the supports.

Filed: 1938-07-02
Abstract: 516,643. Wireless transmitting systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and WASSELL, H. J. H. July 2, 1938, No. 19668. [Class 40 (v)] Multi-valve telegraph transmitters are keyed by controlling the potentials upon the screen grids of some of the valves and arranging that the final keyed valve takes maximum dead loss during " spaces " to prevent excessive load variations upon the power source. A keying valve 2 is connected in series with a resistance 4 across the D.C. supply 1. Keying means 6, 7, 8, is arranged to render valve 2 conductive or non-conductive and taps 9, 10, 11, on resistance 4 supply the screen grids of certain of the valves in the transmitter. The final valve 12 has its screen connected to the positive terminal of source 1 and its control grid 15 by which it is keyed is connected through choke 16 and resistance 17 to a bias source 18 and thence to a tapping 19 on the resistance 4. During "marks" valve 2 is conductive and positive potentials are applied to the screen grids to make the valves conductive, also the potential from tap 19 opposes the bias source 18. During " spaces " valve 2 is non-conductive and the screen grid potentials of the earlier valves falls to zero, rendering them non-conductive. Also the grid bias of the last valve 12 is determined solely by source 18 and is of such a value that the valve takes maximum dead loss. During " marks " a voltage is developed across resistance 17 by grid current which renders the grid of valve 12 more negative during "marks" than during " spaces."
